Application le. June 1Q,y 1926i.` Serial N'o. 115,080.

My invention relates to a 'wind motor employing curved sails and'shields'to determinethe extent of the sail area presentedl to the wind.

rllhe general object of my invention is to provice a novel assemblage ofparts of sim* ple construction and arrangement and etlicient inregulating the sail area presented to the wind and the area shielded aswell as a novel drive assemblage for actuating the driven shaft-g y Thenature of my invention and its distinguishing features and advantages.will clearly appear as the description proceeds.

Reference isto be had to the accompanying drawings forming a part ofthis specification, it being understood that the drawings are merelyillustrative of one example of the invention. f l l Figure 1 is anelevation of a wind motor embodying my invention;

Figure 2 is a vertical section through the chamber containing the drivemechanism and governor, the section being indicated by Figure 3 is ahorizontal section through the rotor;

Figure t is a sectional plan view of the drive mechanism and governor.

ln carrying out my invention in accordance with the illustrated example,a bottom plate isprovided and a top plate 11. Below the bottom plate isa chamber 12containing the drive gearing and governor. A mast 13extends. upwardly through the chamber 12 axially through the rotor aswell as through the top and bottom plates lO and 11. rlhe mast 13 at thetop receives a cap 14 above the top plate 11. Wind shield blades 16 incontinuous arcuate series extend between the plates 10 and 11, one edgeof each of which blades is beaded and receives rods 17 riveted to thetop and bottom plates.

Curved metal sails 18 in annular series are secured to a top plater 19and a bottom plate 20. rlhe beaded edges of said sails 18 receivevertical bolts 21 tying the top and bottom plates 19 and 2O together.The

vbottom plate 20 is secured to a hub 22k revoluble about the mast 13.The casing of thc chamber 12 is secured to the plate 10 by angle irons23. At the opposite side of the motor from the shield 16, shields 24 areprovided in series, the beaded orV turned edges of which receive rivetedrods 25 forming additional tic means between the plates 10 and 11. Saidshields 24: extend about the wheel at the opposite side from the windside.k At one end of the series of shields 24; is a'triangular structure26 and the space between said structure 26 and the near end of theseries of shields 16 defines the wind entrance to the motor. Between theoppo- .site end of the `series of shields 24 and the series of shields16 is a smaller space through which wind finds exit after turning therotor. l

The hub 22 has a broad gear 27 meshing withwliich is a gear wheel 28 onthe power shaft 29. Meshing also with the pinion 27 is a' Vgear wheel 39which in turn meshes.

with a gear vwheel 31 (Figure 4) on the shaft of a. ball governor. Themovable collar 33 of the governor subject to the rising and fallingmovement of the balls, has pivoted thereto, one arm of a bell cranklever 34: fulcrumed as at 35 on a standard 36. rlhe other arm ofbellcrank lever 34 connects bya link 37 ywith an arm 38 on a verticalshaft 39 that rises and projects above the top `plate I11 of the motor.Said shaft 39 has secured thereto the wind vane `With the abovedescribed construction, the turning of the annular series of sails 18 byvwindblowing in the general direction of the arrows in Figure 3, willcause the hub 22 to be revolved and through the pinion 27 and-gear wheel28, the powershaft 29 will 'be' driven. At the same time through thewheels and 31 the governor 32 willib'e revolved. `When the collar 33rises in response to the centrifugal force of the ball governor, themovement of said collar 33 will through bellcrank 3/1, link 31 and arm38, turn the wind vane shaft 39 and swing the wind vane 10 from theposition indicated in dot-and-dash lines in Figure 3 to the obliqueposition indicated by dotted lines in said Figure 3. The wind acting onthe vane 40 will then turn the outer structure bodily about the axis ofthe rotor so that the wind is presented in the direction of the dot-tedarrow in Figure 3, in whichposition of the sail wheel or rotor severalof the sails 18, exposed to the wind, will receive pressure on the backsthereof while a diminishing number of the sails will receive wind in thefront thereof for turning the wheel.

On the mast 13 is a split collar 41 held to mast by bolts 42. Boltsl i3secure a Flange on vthe split collar to a fixed ,floor structure onwhich is mounted a series oit rollers 45, disposed 90 apart. Resting onthe rollers i5 is a platform 4 6 to which the casing of the housing l2is secured by suitable means V'such as angle irons 47. Thus, themechanism in the chamber l2, except the driven gear wheel 28 on thepower shaft is afforded support on or from the platform 46.

I would state 'furthermore that while the illustrated exampleconstitutes a practical embodimentoiI my invention, I do not limitmyself strictly to the exact details herein iilustrated, since,manifestly, the same can be considerably varied withoutA departure 'fromthev spirit oit the invention as defined the appended claims.

Having thus described my invention, I claim:

l. In a wind motor a `wind driven rotor having' an annular series o'l'sails, a mast about the axis of which the rotor turns, a hub on saidrotor turnable with saidA mast,

iixed floor secured to the mast, rollers on the floor at intervals, astructure outside ot the rotor, including a platform resting' on saidrollers, as well as a housing secured to said platform, a power shaft,means to drive said shaft by the turning` of the rotor, a governor, awind vane, said structure being turnable bodily by wind pressure on saidvane, and means to swing said vane by the movements oithe governor, saidgovernor and `said last mentioned means being mounted above saidplatform and the turning` of said structure bodily by the vane servingto reduce or increase the effective sail area of the rotor presented tothe Wind.

2. In a wind motor a wind driven rotor having sails, a casing below saidrotor, top and bottom plates above and below the sails, connectionsbetween said top and bottom plates, said casing below the rotor being secured to said bottom plate, a mast extending v Leads-:eo
